BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a tube structure, and more particularly to a tube structure for preserving a flower.

2. Description of Related Art

The transporting processes of flowers are so numerous and complicated when the flowers are sold abroad or internal. The preserving, package and moisture keeping for the flowers must be under controlled in the transporting processes. The most important issue is how to keep the freshness of the flowers in the transporting processes.

Water is the necessary source for the flowers. The flowers will gradually fade under strong sunshine or lack of water, so that the seller would soak stems of the flowers in the water during the transporting processes for preserving the flowers. Furthermore, the flowers will be hit by each other due to the vibration or compression caused by the transporting processes, so that the flowers will be further damaged. Therefore, a seller would put the flowers into a box and plug the stem of each flower into a conventional tube with water for providing sufficient water to flowers and decreasing the said damage. Under the above arrangement, the sterns must be soaked in the water, because the flowers suck the water via the stems thereof, during the transporting processes.

However, the flowers may be vertically, horizontally or obliquely putted into the box during the transporting processes. For example, when the flowers are horizontally putted into the box and a volume of water equals the total volume of the conventional tube, the flowers can suck the water of the conventional tube steady because the stem is totally soaked in the water; in contrast, when the volume of the water gradually decrease due to the continuous suck of each stem, the flowers cannot suck the water of the conventional tube steady because the stem is just partially soaked in the water and the stem would further be released from a surface of the water. Furthermore, the vibration or compression caused by the transporting processes would make the stem sometimes be placed into the water of the conventional tube and sometimes be deviated from the water of the conventional tube, so that the stem cannot suck the water of the conventional tube steady. Therefore, the said conventional tube can not actually provide preserving effect in the transporting processes.

The present invention has arisen to mitigate and/or obviate the disadvantages of the conventional.

SUMMARY OF THE INVENTION

The main objective of the present invention is to provide an improved tube structure.

To achieve the objective, a tube structure for preserving a flower comprises a body having an assembling portion and a storage portion. The assembling portion is formed as awl-shaped. A bottom of the storage portion is formed as arc-shaped. The assembling portion is defined at a top end of the body. The storage portion is defined at a bottom end of the body. A water chamber is defined in the body. The water chamber communicates with the assembling portion and the storage portion. A surrounding wall is deformable and is formed onto the assembling portion. A through hole is opened on the surrounding wall and communicates with the water chamber. A soft wall is defined around a bottom of the storage portion. A rigid wall is defined around a top of the storage portion. An angle is defined between an inner surface of the surrounding wall and a further inner surface of the rigid wall. The angle is larger than 95 degree. A thickness of the rigid wall is gradually decreased toward the soft wall. The angle is 95 degree to 135 degree. The assembling portion and the storage portion are integrated with each other.

Wherein, when a flower stem is plugged into the through hole, the flower stem forces the surrounding wall to deform elastically. As a result, the surrounding wall firmly positions the flower stem. Under the above arrangement, when the flower stem sucks a volume of water in the water chamber, the soft wall is deformed via a decrease of the water in the water chamber, so that the soft wall presses the water and the water is flowed upwardly.

Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings to FIGS. 1-7, a tube structure for preserving a flower in accordance with the present invention comprises a body 1 having an assembling portion 12 and a storage portion 11. The assembling portion 12 and the storage portion 11 are integrated with each other. The assembling portion 12 is defined at a top end of the body 1. The storage portion 11 is defined at a bottom end of the body 1. A water chamber 13 is defined in the body 1. The water chamber 13 communicates with the assembling portion 12 and the storage portion 11. A surrounding wall 122 is formed onto the assembling portion 12 and is deformable. A through hole 121 is opened on the surrounding wall 122 and communicates with the water chamber 13. A soft wall 111 is defined around a bottom of the storage portion 11. A rigid wall 112 is defined around a top of the storage portion 11. An angle α is defined between an inner surface of the surrounding wall 122 and a further inner surface of the rigid wall 112. The angle α is larger than 95 degree.

Wherein, when a flower stem 2 is plugged into the through hole 121, the flower stem 2 forces the surrounding wall 122 to deform elastically. As a result, the surrounding wall 122 firmly positions the flower stem 2 at the through hole 121. Under the above arrangement, when the flower stem 2 sucks a volume of water in the water chamber 13, the soft wall 111 is deformed via a decrease of the water in the water chamber 13, so that the soft wall 13 presses the water and the water is flowed upwardly for the flower stem 2 to suck.

Referring to the drawings to FIGS. 6-7, when the flower stem 2 is plugged into the through hole 121, the angle α is larger than 95 degree because a cross-section area of the flower stem 2 is larger than the area of the through hole 121 initially (The angle α is well defined between 95 degree to 135 degree), so that the assembling portion 12 is formed as awl-shaped. Under the above arrangement, the flower stem 2 is abutted against the surrounding wall 122 tightly for forcing the surrounding wall 122 to deform elastically along a plugging direction of the flower stem 2. Therefore, the flower stem 2 can be firmly positioned at the through hole 121 so as to prevent the flower stem 2 from dropping down from the through hole 121.

Referring to the drawings to FIGS. 4-7, when the flower stem 2 sucks the water of the water chamber 13 gradually, an air pressure of the water chamber 13 would be smaller than an outer atmospheric pressure; then, the soft wall 111 would be pressed and be deformed inwardly by the outer atmospheric pressure; thereafter, the soft wall 111 presses the water of the water chamber 13; as a result, the water of the water chamber 13 is flowed upwardly; therefore, the flower stem 2 would be always soaked in the water of the water chamber 13 even though the flower stem 2 is placed horizontally or obliquely. All in all, the presented invention can avoid the disadvantage of a conventional tube, in which the flower stems would fade easily in the transporting processes.

Referring to the drawings to FIGS. 2-3, the rigid wall 112 is defined between the soft wall 111 and the assembling portion 12. A hardness of the rigid wall 112 is larger than another hardness of the soft wall 111, because a thickness of the rigid wall 112 is gradually decreased toward the soft wall 111, so that the rigid wall 112 cannot be pressed and deformed easily. Referring to the drawing to FIG. 8, a user can hold the rigid wall 112 to pull the flower stem 2 out from the body 1 steady, and the water of the water chamber 13 would not overflow the body 1.

Furthermore, the soft wall 111 is defined at a bottom of the rigid wall 112. When the flower stem 2 sucks water of the water chamber 13, the soft wall 111 would be pressed and deformed inwardly by the outer atmospheric pressure from a bottom of the soft wall 111 to a top of the soft wall 111 which is connected to the rigid wall 112. Therefore, the water of the water chamber 13 is flowed upwardly for the flower stem 2 to suck via the above deforming of the soft wall 111.

Referring to the drawing to FIG. 1, the through hole 121 is opened on a top of the assembling portion 12, so that when the flower stem 2 is plugged into the through hole 121, the assembling portion 12 would be forced to be deformed as reverse awl-shaped. The flower stem 2 would be abutted against the surrounding wall 122 tightly. Besides, a bottom of the storage portion 11 is formed as arc-shaped, so that the storage portion 11 can be pressed and deformed easily for forcing the water of the water chamber 13 to flow upwardly.
